Have you ever walked around your home after coming in from outdoors only to realize your shoes were a bit dirtier than you had assumed? If so, then you'll love the latest invention from Japan's Palonia Furyokuki company: An industrial-quality doormat which sucks unwanted debris off the bottoms of your soles simply by walking across it.
The metal-clad walkway is equipped with hundreds of small, rubberized
buttons that form a seal. When the built-in motion sensor detects
someone walking by, it automatically turns on a vacuum system beneath
the doormat. Then, when your shoe pushes down on the buttons, the vacuum
sucks all the dirt that was on your shoes into the mat itself. The dirt
is collected in removable drawers for easy disposal.
